Abstract

The invention discloses a touch display panel and a display device which aim to improve the problem that the signals between the touch electrodes at different positions of a touch display panel in theprior art are different, so that the touch performances of different positions of the same touch panel are different. The touch display panel comprises a display area located on one surface of a substrate and a non-display area surrounding the display area, the display area is provided with a plurality of first touch electrodes extending along a first direction, and the non-display area is provided with a plurality of first touch wires correspondingly and electrically connected with the first touch electrodes. The routing lengths of the first touch routing wires are different, and the different first touch routing wires adopt at least one of the following modes to enable the resistances of the first touch routing wires to be consistent. The different first touch routing wires are providedwith different numbers of first via holes, and have different wire widths.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, in particular to a touch display panel and a display device. Background technique [0002] Nowadays, due to the rapid development of the display technology level, the application range of the touch display screen is more and more extensive. At present, the touch technologies mainly involved in the touch display screen are divided into self-capacitive touch and mutual-capacitive touch. [0003] However, in the mutual capacitive touch display panel of the prior art, there may be differences in the signals between the touch electrodes at different positions (for example, there are differences in the signals obtained between the driving electrodes at different positions, and there are differences between the sensing electrodes at different positions. There are differences in the signals obtained between them), which leads to the problem that the touch performance of different position...
